Elder Zheng patiently explained to Mo Hua.
Mo Hua nodded slowly, deep in thought, "So by that logic, a Second Grade Formation Master could theoretically activate a Third Grade Formation too?"
"In theory, yes, but the requirements are pretty strict," Elder Zheng said. "First, these kinds of Formations have to be created from the very beginning with the intent to reduce costs and increase efficiency, designed and constructed using the 'demotion-pattern' technique."
"Second, a Second Grade Formation Master can't draw these Formations themselves; at most, they can just operate them."
"After all, it's still a Third Grade Formation. Without sufficient Realm, even if you can operate it, its effect is greatly diminished."
"Also, the usage requirement for these Formations is Divine Sense."
